Definitions
- This invention relates generally to connectors for making an electrical connection between each of one or more insulated wire leads and each of one or more other insulated or uninsulated wires. More particularly, this invention relates to connectors of such kind which do not require the use of any tool to make such connection, and which are insulative displacement connectors in the sense that they comprise an insulative base and insulative housing and are operable to make such connection by relative displacement of these two insulative elements.
- U.S. Pat. No. 4,913,659 issued Apr. 3, 1990, in the name of Clarence E. Doyle for "Push Cap Terminals and Terminal Boards with Same” discloses an electrical connector comprising a terminal for an insulated wire lead comprising an upstanding insulative housing, electroconductive means disposed at least partly in such housing and having a portion connectable to a wire, a cap initially seatable in an up position on said housing, and adapted to be forcibly pushed down from said up position to a down position on said housing, and means permitting insertion of said lead into the space enclosed by such housing and cap and for effecting connection in said space of said inserted lead with said electroconductive means.
- the terminal disclosed in such patent has been very satisfactory in the application therefor which it is disclosed in that patent, and which is as one of a plurality of insulated wire lead terminals (there being one such terminal per lead) mounted on a terminal board ordinarily connected up and otherwise serviced by experienced telephone company technicians.
- That disclosed terminal would, however, have the disadvantages, if provided for its connecting up, by technically unskilled persons, that the cap of the terminal detaches too readily from its housing, and that the connection in the connector of the wire lead inserted therein may be too easily opened up by pulling force exerted on the lead and causing the lead to slide out from the terminal strip by which it was previously gripped.
- connection according to the invention is not, however, necessarily limited just to a connector providing one or both of such improvement features but, rather, may be any connector defined by any of the claims hereof.
- FIG. 1 is an exploded perspective view of an exemplary embodiment of connector according to the invention and of exemplary electrical conductor means adapted to be interconnected by such connector;
- FIG. 2 is an exploded perspective view of the FIG. 1 connector and conductor after assemblage with the base of the connector of the connector's terminal strips and of a stub telephone cord terminating in a modular plug;
- FIG. 3 is a plan view of the base or housing of the FIG. 1 connector without the terminal strips being mounted therein;
- FIG. 4 is a right side elevation of the FIG. 3 housing as partly broken away to show interior portions thereof in cross section;
- FIG. 5 is a front elevation of the cap of the FIG. 1 connector, the cap being partly broken away to show interior portions thereof in cross section;
- FIG. 6 is a right side elevation of the FIG. 5 cap as partly broken away to show interior portions thereof in a cross section;
- FIG. 7 is a right side elevation of the connector as shown in FIG. 2 with the cap being seated in up position on the housing and the wire leads shown in FIG. 1 being inserted in to the cap;
- FIG. 8 is a right side elevation of the FIG. 1 assemblage when the cap has been manually forced to its down position with the housing;
- FIG. 9 is a split view with the left half of the drawing being a front elevation of the FIG. 8 assemblage, and the right half of the drawing being a front elevation in cross section of that assemblage.
- Connector 20 comprises the components of a pair of electroconductive means 21a, 21b in the form of metallic, vertically extending terminal strips, a molded plastic insulative base or housing 22 for the strips 21, and a cap 23 for those strips.
- Connectors according to the invention may comprise a plurality of individual terminals each adapted to connect one wire to another wire.
- the connector is such a multiterminal connector which, as indicated by the dashed dividing line 24 on housing 22, is divided into duplicate left-and right-hand terminals 25a and 25b disposed side by side in the lateral dimension and containing, respectively, the terminal strips 21a and 21b.
- FIG. 1 Shown in FIG. 1 in association with connector 20 are the free ends of a pair of insulated wire leads 30a, 30b comprising metallic cores 31a, 31b and insulated jackets 32a, 32b around these cores.
- the leads 30 are tip and ring leads for a telephone set (not shown) disposed in, say, an apartment building at a location away from their shown free ends which may be, say, in the cellar of the building.
- a stub cord 40 comprising a conventional modular telephone plug 41 adapted to be inserted into a mating modular jack to connect the mentioned telephone set to a telephone network, a plastic ribbon 42 fastened to and extending away from plug 40, and a pair of electrical wires 43a, 43b embedded in ribbon 42 and extending from connections with plug 41 through ribbon 42 to bare ends 45a, 45b of such wires extending out from the free end of ribbon 42.
- the terminal strip 21a is made of phosphor bronze or some other resiliently deformable electroconductive material, and the strip comprises a lower downwardly projecting stem 50a, a shank portion 51a above such stem and a support column 52a extending from such shank portion to an upper section 53a.
- Upper section 53a is a bifurcated section comprising a pair of tangs 54a, 55a separated by a contact gap 56a in the lateral dimension and resiliently deflectable away from each other in that dimension.
- the tangs 54a, 55a bear thereon respective cutting edges (not shown) adjacent to the gap 56a.
- Terminal 21b is a duplicate of terminal 21a. These terminals are similar to the terminal strip disclosed in the aforementioned Doyle patent, incorporated herein by reference and made a part hereof, which provides more details on the characteristics of the terminal strips 21 described herein.
- a central chamber 60 (FIG. 7) peripherally enclosed by (FIG. 2) vertical front and back longitudinally-spaced walls 61, 62 and by vertical laterally spaced left- and right-hand side walls 63 and 64.
- compartment 60 is closed (FIG. 9) by a bottom 65.
- Upstanding from bottom 65 are a pair of support pedestals 66a, 66b (FIG. 3).
- Pedestal 66a has formed therein a vertical slot 67a passing downward through the pedestal and through the compartment bottom 65.
- Pedestal 66 has a similar slot 67b therein.
- the shank portions of the terminal strips 21a, 21b are seated with a tight fit in, respectively, the slots 67a, 67b in the pedestals 66a, 66b so that the stems 50 of those terminals project downward beyond the underside of compartment bottom 65, and so that the upper sections 53a, 53b of the terminal strips are positioned upwards (FIG. 2) of the chamber 60 in the housing.
- the stems 50 of these strips are peripherally enclosed by a skirt 59 extending on housing 22 downward beyond its chamber bottom 65.
- the chamber 60 is partly closed at its top by a shelf 70 (FIG. 1) extending laterally across the housing 22 at its front. Longitudinally behind the shelf the chamber has a top opening 69 bounded at its rear by a ledge 68 (FIG. 7) projecting inwards from the top of back wall 62 of the housing. Extending into shelf 70 from its back side are two centrally located, rectangular, relatively wider and narrow notches (not numbered) of which the wider one extends into the shelf for a lesser distance than does the narrow notch. These two notches form in the top of the housing a guide passage 71 having laterally opposite margins of stepped configuration.
- the portions 72a, 72b of the shelf 70 which are on opposite sides of the laterally narrowest part of the guide passage 71 (and are also adjacent to the front housing wall) are shelf portions providing downward facing stop shoulders 73a, 73b. The significance of those shoulders will be later discussed.
- a pair of probes 75a, 75b located on portions 74a, 74b of the shelf adjacent to its back side and on laterally opposite sides of the laterally widest part of the guide passage 71.
- Those probes are of square horizontal cross section and project upward from those shelf portions.
- the probes 75a, 75b at their top have slanting front and back faces 76 and 77 which meet at laterally extending edges 78 to form dihedral angles defined by those faces.
- the top triangular tips 79a, 79b of the probes 75 formed by the faces 76, 77 are convexities of which the outward surfaces have respective inflections 83a, 83b in the upward vertical direction relative to a horizontal surface passing through such tips.
- the housing 22 at its back has a molded plastic portion integral with the rest of the housing and providing a clip 80 therefor.
- the clip 80 has formed therein a deep horizontal notch 81 extending into the body of the clip from its left side (FIG. 3) and adapted to receive and retain therein (FIG. 7) the ribbon 42 of the stub cord 40.
- the clip 80 also has formed therein a smaller vertical notch 82 for receiving therein a projecting rib (not shown) of a device which is adapted to receive and mount therein the connector 20. That device may be, say, a building entrance protector device in the cellar of the mentioned apartment building.
- the stub cord 40 is fastened to the housing 22 by providing wire wound couplings 85a, 85b (FIGS. 9 and 8) of the bare wire ends 45a, 45b of the wires 43 of the stub cord to the downwardly projecting stems 50 of the terminal strips 21 contained in the housing.
- the ribbon 42 of the stub cord is forced into the notch 81 in the clip portion 80 of the housing to be frictionally retained in that notch.
- the cap 23 at its top has a head 90 which is mostly solid plastic but has therein various passages soon described.
- the head At its front, the head has a pair of forwardly projecting noses 91a, 91b.
- a downwardly extending web 92 Integrally joined to the underside of head 90 is a downwardly extending web 92 having a bottom 93 and dividing on longitudinally opposite sides of such bottom into front and back downwardly extending legs 94 and 95 spaced longitudinally far enough apart that they are adapted to straddle the pedestals 66 in housing 22 when (as later more described) the cap is forced down into the housing 22 (FIG. 8).
- the legs 94 and 95 are longitudinally joined by a central crossbraces 86 (FIGS.
- cap 23 is of "H" shape in its horizontal cross section below web bottom 23.
- the leg 95 of the cap carries on its back side (FIG. 6) a rearwardly projecting horizontally extending detent ridge 96 and a rearwardly projecting horizontally extending rounded detent rib spaced on the leg a short distance above ridge 96 leg.
- Ridge 96 provides on its top a slanting detent shoulder 98 and, on its outer side, a wedging face 99.
- the web 92 has formed therein a pair of vertical channels 101a, 101b extending from the web bottom 93 upward through the web and then through the head 90 to terminate in openings therefor at the top of the head.
- Such passages 101 register with and are adapted to receive therein the terminal strips 21 projecting upward (FIG. 2) from the housing.
- Other passages in the cap are a pair of horizontal circular bores 102a, 102b extending from the front of hoses 91a, 91b rearwardly through those noses and head 90 to intersect with, respectively, the channels 101a, 101b and to then extend rearwardly beyond them into a projecting overhang 103 of the cap.
- the bores 102a, 102b have blind ends for which, however, communication to the outside of the cap is provided by slit windows 104a, 104b.
- the bores 102a, 102b define paths 105a, 105b (FIGS. 1 and 2) for insertion of the leads 30a, 30b, into the cap and then to the channels 101a, 101b and post them into the overhang 103.
- apertures 110a, 110b having a square horizontal cross section slightly greater in size than the probes 75 on housing 22 and adapted to receive those probes.
- the apertures 110a, 110b extend in cap 23 upward from the bottoms of noses 91 to intersect with, respectively, the bores 102a, 102b and to then extend slightly upwards beyond them to terminate in top ends 111a, 111b of such apertures.
- the portions 114a, 114b of connector 20 into which the top ends of those apertures penetrate are portions which have grooves 115a, 115b formed therein by such top ends.
- the wall surfaces of such grooved portions have respective inflections 116a, 116b in the upward vertical direction relative to the surfaces of such portions bounding bores 102 to either longitudinal side of the grooves 115, and the portions 114 providing such inflections are portions having concavities therein.
- the cap 23 includes as an integral part thereof a resiliently deformable cantilever beam 120 having a lower fixed end 121 integrally coupled with the front cap leg 94 on the front side of that leg (FIG. 6). From that fixed end, the beam 120 extends upwardly and forwardly to a free end 122 adapted to serve as a key button. In so extending upward, the beam passes through a slot provided laterally between the cap noses 91 to accommodate the beam.
- Beam 120 above its fixed end comprises a lower section 125 of full lateral width and an upper section 126 of reduced lateral width relative to section 125. That width reduction of the upper section produces on laterally opposite sides of the lower section 125 at its top a pair of upwardly facing stop shoulders 130a, 130b.
- the lower section 125 comprises part of a cap latching means while the upper section 126 constitutes a cap releasing means.
- the lower section 125 has "cut-away" portions 127 which are disposed in that section around portions of a middle ridge 128 of the same longitudinal thickness as upper section 126, and which portions 127 are of reduced longitudinal thickness relative to elements 128 and 126.
- the lower section 125 has on its outside a slanting detent shoulder 129 and a wedging face 124 below that shoulder.
- the cap 23 is assembled with housing 22 (with the latter already including terminal strips 21, and being fastened to cord 40) so that the cap is seated in the up position on the housing.
- housing 22 With the cap being initially spaced above the housing as shown in FIG. 2, the downward end of the cap is lowered into the top opening 69 of the housing to cause the wedging faces 99 and 124 on the cap to first engage with, respectively, the ledge 68 and the shelf portions 72 of the housing at the back and front, respectively, of that opening and to then move down past these engaged housing elements.
- the cap is only yieldably detained in that, because of the slant of the detaining shoulders 98 and 129, the cap by moderate lifting force thereon can be pulled up and away from the housing, and in that moderate downward force on the cap will cause the detent rib 97 to move down past ledge 68 and thus free the cap for further downward movement.
- the wire leads 30 are guided along the shown paths 105 therefor to insert those leads into the bores 102 in the cap, and past the intersection of those bores with the channels 101 and then in such bores into the overhang portion 103 of the cap. The insertion of the leads is then stopped by the coming into contact of the free ends of such leads with the blind ends of the bores 102 in the overhang 103.
- the cap 23 is forcibly pushed by hand into housing 22 to have the following effects.
- the downward driving of the cap into the housing produces a relative movement of the probes 75 on the housing upward into the apertures 110 in the cap until such movement is stopped either by the legs 94, 95 of the cap contacting the housing bottom 65 or by the head 90 of the cap contacting the housing's top.
- the leads 30 inserted into the bores 102 in the cap are slightly smaller in diametral size than the bores, and the grooved portions 114 of the cap bordering those bores and the convex tips 79 of the probes constitute upper and lower lead contacting means, respectively which are disposed in vertically registering relation on opposite sides of each of the paths 105 for the leads.
- the respective surfaces of the grooved portions 114 and the convex probe tips 79 constitute matching inflections 116 and 83 in the same upward vertical direction from the horizontal lie of the bores 102.
- the leads 30 are each contacted on opposite sides by the mentioned upper and lower lead contacting means, and the convex tips 79 of the probes press against, and force into the grooves 115, the portions 140 adjacent thereto of the leads 30 so as to produce in these leads inflections 141 in the upward vertical direction relative to the lead's horizontal lie elsewhere in the bores.
- Such inflections in the leads match the surface inflections 116 and 83 provided by the grooved portions 114 and the convex probe tips 79.
- Such strain relief may be realized in connector 20 in one or both of two different ways.
- a second way to provide such strain relief is to design connector 20 so that an incremental amount of the downward displacement of the cap, produced at the end of its downward movement, is communicated by the inserted leads 30 to the probes 75 to resiliently depress the shelf portions 74 on which those probes are mounted, and so that, after all relative movement between the cap and housing has ceased, at least a fraction remains of that downward resilient deflection of the shelf portions.
- the resilient stress still existing in those shelf portions will urge the probes 75 upward to cause the elements 79 and 114 to frictionally grip between them the lengthwise distributed adjacent portions 140 of the leads under the upward vertical force exerted by the probes so as to produce in the leads 30, when needed, a friction force directed to oppose the pulling force on the leads.
- the lower section 125 of the cantilever beam 120 on the cap slides down past the shelf portions 72 of the housing in contact with such portion to be resiliently bent into a bow shape by such contact and sliding to thereby incrementally shorten the chordal length between the fixed end 121 of the beam and the upward facing stop shoulders 130 on the beam.
- Those stop shoulders are so positioned in the length of the beam that, when the downward pushing of the cap into the housing is arrested, those stop shoulders will be lower by a clearance than the adjacent downward facing stop shoulders 73 provided by the undersides of the shelf portions 72.
- the resiliently deformed lower section of the beam will spring back toward its original undeformed position so as, by a snap-fitting action, to position the lower upward-facing shoulders 130 on the beam 120 of the cap beneath the upper downward-facing shoulders 73 on the housing 22.
- the result is that, upon the application to the connector 20 of force which is solely lifting force exerted on the cap, the cap cannot be detached from the housing because, although such lifting force urges cap 23 as, a whole and its beam shoulders 130 upward, that upward urging is equally and oppositely opposed by a downward force 7hich is exerted by the housing shoulders 73 on the cap carried shoulders 130, and which downward restraining force progressively becomes greater as the upward urging force becomes greater.
- the described shoulders 73 and 130 and associated parts of the connector 20 thus provide for each of the terminals 25a 25b in the connector a latch means operable when the cap 22 is in its down position on housing 22 to unyieldably restrain it (short of breakage of parts) form being detached from the housing in response to application to the connector or terminal of force which is solely lifting force exerted in the upward direction on the cap.
- That latch means provides the advantage that the cap cannot be casually detached from the housing so as to cause exposure of the electrical connections within the connector.
- Another advantage is that such latch means is automatically actuated in response to the downward pushing of the cap to provide its latching effect, so that it is not left to chance.
- cap 23 While the cap may be latched permanently as described to the housing, there may, however, be instances when it would be desirable to remove cap 23 from housing 22. Such removal may be accomplished by the use of the cap releasing means provided by the upper section 126 of the beam 120 in the cap. To effect such removal, rightward horizontal force (FIG. 8) is exerted by hand on the key button provided by the free end 122 of section 126 of beam 120 to resiliently bend the beam to bring it to a position at which the shoulders 130 thereon become disengaged from the shoulders 73 on the housing. Then as long as the beam is held by hand in that position, the cap 23 may readily be lifted up to separate it from the housing 22.
- rightward horizontal force (FIG. 8) is exerted by hand on the key button provided by the free end 122 of section 126 of beam 120 to resiliently bend the beam to bring it to a position at which the shoulders 130 thereon become disengaged from the shoulders 73 on the housing. Then as long as the beam is held by hand in that position, the
- any play in the vertical direction of the relative positioning of the cap and housing can be ended by providing for resilient deflection downward of the housing shelf portions 74 as earlier described, and, after the cap has been pushed as far as possible down into the housing, by utilizing that deflection of those shelf portions 74 to act through probes 75 and leads 30 to produce in the positioning of the cap an incremental upward rebound which eliminates all clearance between the shoulders 130 and 73 and brings them into pressure contact maintained by the remaining resilient stress in the deflected shelf portions 74 and/or by residual resilient compression in the insulation of the leads 30.
